Clicking Ok adds the resources to the source
Managing Search Indexes We will now look at the Search Indexes list at the bottom of the Search Management screen. Previously, we created a new index called Playground. It should be displayed at the top of the Search Indexes list. At the beginning of each entry in this list, there are four buttons. The first, a blue expanding folder, loads the Edit screen for the index. There you can change the rebuild mode, the locale, and the project for that index. (We set these when we created the new index.) The second button, a green book in front of a blue expanding folder, loads the Assign index sources screen. This screen allows us to specify which sources to use with this index. To add the Playground Source source that we created earlier, we can select it from the list on the right and click the Add index sources button. This will add the item to the Index sources list, which indicates that this index is now using our new source.
